Struct Fields

Reflection can enumerate a struct type's fields and names.

struct_fields.go

package main

import (
	"fmt"
	"reflect"
)

type User struct {
	Name  string
	Level int
}

func main() {
	var level = 
	user := User{Name: "Ada", Level: level}
	userType := reflect.TypeOf(user)
	firstField := userType.Field(0)
	secondField := userType.Field(1)

	fmt.Println("level=", level)
	fmt.Println("type=", userType.Name())
	fmt.Println("field_count=", userType.NumField())
	fmt.Println("first_field=", firstField.Name)
	fmt.Println("second_type=", secondField.Type.String())
}

package main

import (
	"fmt"
	"reflect"
)

type User struct {
	Name  string
	Level int
}

func main() {
	var level = 
	user := User{Name: "Ada", Level: level}
	userType := reflect.TypeOf(user)
	firstField := userType.Field(0)
	secondField := userType.Field(1)

	fmt.Println("level=", level)
	fmt.Println("type=", userType.Name())
	fmt.Println("field_count=", userType.NumField())
	fmt.Println("first_field=", firstField.Name)
	fmt.Println("second_type=", secondField.Type.String())
}

package main

import (
	"fmt"
	"reflect"
)

type User struct {
	Name  string
	Level int
}

func main() {
	var level = 
	user := User{Name: "Ada", Level: level}
	userType := reflect.TypeOf(user)
	firstField := userType.Field(0)
	secondField := userType.Field(1)

	fmt.Println("level=", level)
	fmt.Println("type=", userType.Name())
	fmt.Println("field_count=", userType.NumField())
	fmt.Println("first_field=", firstField.Name)
	fmt.Println("second_type=", secondField.Type.String())
}

struct fields Use field metadata when a framework or helper needs to inspect the shape of a struct.
